to fit the heater loom you mean? Nah it's a one hour job, I have done (easily 45-50) and never taken dash out. The only time it's probably best to remove dash is on LED display climate control models as you need to get to solar sensor and upper flap motor.

I'm fairly sure they are 1.2w not 2.3w aren't they?

Also, that guide suggests you remove the stereo. There is no need to remove the stereo, you can remove a small trim panel from the footwell and get your hand up in from behind.

As promised, see the attached photos, they show it better. They show the new and old connector, cut down, burnt connector in comparison to the new one, new connector fitted, end result, it works a treat.

I tried and failed to remove it so I took a photo with the camera and had a look at it that way! I could see it was in perfect order so was happy to buy the replacement part knowing it would fit.

Thumbs up Re: Burnt wiring in heater

Chinqster355 you're an absolute star...

I have had exactly the same problem with the heater in my daughter's GP and initially I simply wiggled the wires and connector block and the heater started working again.

However, since reading your thread I've investigated further and indeed both the plug and loom shows signs of burning.

So on your recommendation I've purchased a Corsa loom repair kit from eBay at a cost of 30 + 3.25pp (the photo and GM part number was identical to yours), so it should be an easy repair.

Just to point out that if anyone else goes looking for the repair loom it's titled 'CORSA D HEATER RESISTOR HARNESS REPAIR KIT'.

Thanks again, your photos and advice have been a great help.

Hello there,

Re: Burnt wiring in heater

Sort of, thanks.

I know I defin don't want to replace the whole loom now.. Got the parts lined up, but I'm just not sure what type of connectors to use when the wires are crimped?

Anyone got any idea what the ones above in the photos are? I've been to maplins today and they've got loads of different types..

Anyone know the wire thickness for example??

Thanks

Re: Burnt wiring in heater

To add to an old thread I have an mjet with climate control and air con. I may be being thick but I can't find this location in the place shown in pictures. Does anyone have a picture of where it would be on my car? The issue I have is that I can be set to full power and it'll turn itself down and back up over and over and gets annoying. I don't have it set to full auto mode either for the record so fully in my control??????

Re: Burnt wiring in heater

@KBonnie, I have the same issue with my 2006, 1.4 with climate control. The fan won't run at high speed for more than a second or so, and then turns itself back down. It keeps trying to get to full speed, but then goes back to slow.. Also I am not on full auto.
